Calcium carbonate (CaCO,. is commonly used as. 3. a flux in the ceramic industry. It occurs naturally in some clays and is added to most white ware bod1$ other than hard paste porcelains to increase the degree of vitrification. It was proposed, therefore, to replace the calcium carbonate in a whiteware body with the halitic salts of calcium.

Calcium fluoride, commonly called fluorspar or fluorite, is the principal fluoride‐containing mineral. Large deposits of flurospar are found in China, Mongolia, Mexico, Spain and South Africa. Underground mining procedures are used for deep fluorspar deposits and open‐pit mines are used for shallow deposits or where conditions do not ...

In dry environments, calcium fluoride can be used up to 1000°C, but it does not begin to soften at 800°C. Calcium fluoride is inert to organic chemicals and many acids, including HF. It will slowly dissolve in nitric acid. Fabrication: Calcium fluoride can be machined with standard diamond tools and water-based coolants. The material
